Makhai were the spirits of battle in Greek mythology, children of Eris, goddess of strife. They had numerous siblings, including Horcus, Ponos, Algea, the Hysminai, Limos, the Phonoi, the Androktasiai, the Neikea, the Pseudologoi, the Amphilogiai, Dysnomia, Ate, and Lethe. They were all personifications of wrong doings or negative situations, such as pain, fights, murder, lies and forgetfulness.

They would appear in battles alongside other spirits and gods linked to war; some of them were the god of war Ares, his followers Deimos and Phobos, the Keres, Enyo, and Eris. Other spirits associated with the Makhai were Homados, spirit of the battle noise; Alala, spirit of the war cry; Proioxis, spirit of the onrush; Palioxis, spirit of the backrush; and Kydoimos, spirit of confusion.
